In 1983 this is what Arthur Collins said. It's harsh but very easy to do.
When a combatant rolls a natural 20 in melee, his opponent (if armored) must roll a saving throw vs crushing blow. Magic armor gives bonus.
A failure means the armor loses 1 AC
Shields are lost first then armor.
Shield +1 becomes magic shield +0 then destroyed.
Plate Mail becomes AC 4
Damaged armor can be repaired at 25gp and 3 days per AC loss.
Magic armor needs a magic user to fix.
A natural roll of 1 means the weapon is notched and becomes -1 'to hit' and damage.
A magic sword becomes magic sword +0 (allowed saving throw vs crushing blow unlike normal weapons).
No edged weapon can be reduced to the point where one cannot possibly hit with it, nor to the point where it can do no damage.
A natural roll of 1 means the weapon has fallen from the characters hand.
Strung Missile Weapons
A natural roll of 1 means the string has snapped. A wet string will snap on a roll of 1 or 2.
Pole arm or staff
A natural roll of 1 means the weapon has cracked (saving throw vs crushing blow allowed)
Hurled Weapon (or Unarmed combat)
A natural roll of 1 means the thrower has fallen off balance. Roll vs Dexterity or lose Dex and shield bonus and is -(1-4) on the initiative roll next round.
A character must attend to his armor and weapons a mininum of four times a year. Else -1 on any saving throw for the items.
In tropical and marsh environments, every week the character must spend all day tending to their weapons and armor.
For Interest DMG has these saving throws vs crushing blow:
Metal hard 6
Wood or rope, thick 10
But the description for crushing blow is a weighty falling object or blow from an ogre's or giants weapon.
A saving throw vs blow normal is described as an attack by a normal-strength opponent or only a fairly heavy object which strikes the object. This seems much more relevant for the above rules by Arthur Collins in which case the saving throws are:
Metal hard 2
Wood or rope, thick 3
This certainly offers more danger to attacks from ogres, giants and dragons. You survive but your equipment may not.
All up I quite like these rules.
